that's right! thanks a lot

[WyattWutang]

Is "xấu tính" similar to "khó tính"? Both seem to me to mean something similar like "bad" or "hard" personality (tính). I mention "khó tính" because that's what was described in another Vietnamese class as the closest meaning to the adjective "mean"

[Anthony863489]

I'd say "khó tính" is more like strict or stern or being inflexible. On the other hand, "xấu tính" is more like having a bad personality hence mean.

[John415149]

why is that we can just use không here instead of không phải là?

[Monk162462]

Because xấu tính is an adjective. là is used with nouns.
